A lot like dry docking. After you completely empty the toilet of water commence with some good upper decker action. The lack of water makes it a lot like a dry dock. The fact that it is in the tank making it above the bowl gives it the term "Sky Docking"

My boss wouldn't give me a raised for the sencond time in a row, so i decided to give him unforgettable experience of a good sky docking. It took him forever to figure out where the brown water was coming from. Can you say ready-made gravy?
